Claude Pro: personal marketplace “already added” but

Claude Pro: personal marketplace “already added” but invisible in UI — plugin stuck on an old version

Hi everyone,

I’m developing SkillPilot, a curriculum-guided learning coach, and its Claude plugin combining MCP, an interactive UI, and Skills. I’m trying to establish a straightforward installation and update workflow for beta testers using their own Claude accounts.

I’m currently stuck with a personal GitHub marketplace on my Claude Pro account. This concerns Claude’s plugin-management UI, not the Claude Code CLI or Team/Enterprise administration.

Marketplace: https://github.com/enpasos/skillpilot-claude-marketplace

Plugin: SkillPilot Coach v1 (skillpilot-coach-v1) Version currently in the repository: 1.1.1 Version Claude still shows after reinstalling: 1.0.4

What happened

I added the marketplace and successfully installed version 1.0.4.

I then published version 1.1.1 to the repository, but Claude continued to show the installed plugin as 1.0.4. I uninstalled the plugin to try a fresh installation.

When I tried adding the marketplace again, Claude rejected it with the German message “Dieser Marketplace wurde bereits hinzugefügt” — “This marketplace has already been added.” Clicking “Synchronisieren” (“Sync”) made no observable difference.

I could find the plugin again under “Entdecken” (“Discover”) and reinstall it, but Claude still showed version 1.0.4.

The part I cannot resolve

The marketplace itself has never appeared as a manageable source in my UI — including before I uninstalled the plugin.

Claude therefore seems to recognize the existing registration, but I cannot find an entry through which I can inspect, refresh, or remove it. Re-adding the same repository is blocked.

The official help article Use plugins in Claude, under Add or remove plugin marketplaces, describes removing a marketplace through its menu in the Plugins section. I cannot find the marketplace entry needed to follow that procedure. ([Claude Hilfecenter][1])

Repository details

The repository is public. On main, the file

plugins/skillpilot-coach-v1/.claude-plugin/plugin.json

declares "version": "1.1.1".

The catalog at .claude-plugin/marketplace.json points to "source": "./plugins/skillpilot-coach-v1". The version is declared in the plugin manifest rather than duplicated in the marketplace entry.

This looks consistent with stale marketplace or plugin metadata, but I have not established the underlying cause.

Questions

Where should a personally added GitHub marketplace appear for a Pro user, and how can I remove or reset its registration when that entry is missing?
Is there a supported way to force Claude to fetch the current repository state rather than reinstalling the version it already knows about?
Has anyone encountered this combination of “already added,” no visible marketplace entry, and an outdated plugin version? Is there a refresh step or repository requirement I am missing?

I’d appreciate a concrete workflow that has worked on a personal Pro or Max account, or pointers to an existing bug report.

Update: marketplace controls found; auto-sync questions remain*

On my personal Claude Pro account I found: Plugins → Add → Manage marketplaces → ⋮

The menu offers Check for updates, Automatically sync, and Remove. Removing a marketplace also uninstalls its plugins. The missing-controls question is resolved for me.

Before finding this, re-adding https://github.com/enpasos/skillpilot-claude-marketplace?v=2 made 1.1.1 appear as current. The Contents tab now shows both 1.0.4 and 1.1.1. I haven't established whether the workaround created another marketplace registration.

Auto-sync and GitHub permissions

Claude says auto-sync requires the Claude GitHub App to have repository access. The authorization screen allows selecting specific repositories, but requests read/write access to code, workflows, Actions, checks, issues, discussions, pull requests and repository hooks.

Could someone from Anthropic clarify:

Sync triggers: For personal marketplaces, does a push to the default branch trigger sync, or is a merged PR and/or plugin version bump required? When do installed plugins adopt the synced update?
Publisher vs. users: Is installing the GitHub App on the publisher's repository sufficient for users on separate Pro accounts to receive automatic updates, without connecting GitHub themselves?
Least privilege: Why are code/workflow write permissions requested for marketplace synchronization? Is a narrower permission set available?

This concerns Claude Web on personal Pro accounts, not the Claude Code CLI or organization-managed marketplaces. I'm trying to establish a reliable update workflow for our beta testers with minimal GitHub access.
